WebOct 24, 2016 · Curly arrows are used to show how the mechanism proceeds. Quite simply, they represent the movement of a pair of electrons in the breaking or forming of a covalent bond. If a covalent bond is breaking, the curly arrow will originate at that bond and this should be clearly shown in your mechanism. WebJan 21, 2024 · When asked to draw a mechanism, curved arrows should be used to show all the bonding changes that occur. A few simple lessons that illustrate these concepts can be found below. Lesson 1 If we remove the pair of electrons in a bond, then we BREAK that bond. This is true for single and multiple bonds as shown below:

Arrow pushing or electron pushing is a technique used to describe the progression of organic chemistry reaction mechanisms. It was first developed by Sir Robert Robinson. In using arrow pushing, "curved arrows" or "curly arrows" are drawn on the structural formulae of reactants in a chemical equation to show the reaction mechanism. The arrows illustrate the movement of electrons as bonds between atoms are broken and formed. It is important to note that arrow pushi… WebThis reaction follows an SN1 reaction mechanism.
